The bill establishes a child tax credit for resident individual taxpayers in Kansas, effective for tax year 2025 and subsequent years. The credit amount varies based on the taxpayer's adjusted gross income, with a maximum credit of $600 for those earning up to $25,000, decreasing incrementally to $25 for those earning over $350,000. Married individuals filing separately can claim half the credit amount they would have received if filing jointly. Additionally, the bill mandates that all income thresholds and credit amounts will be adjusted annually based on the cost-of-living adjustments as determined by federal law.

The legislation also outlines the criteria for a "qualifying child," which includes age, residency, support, and relationship to the taxpayer. It stipulates that if the credit exceeds the taxpayer's income tax liability, the excess will be refunded. Furthermore, the Secretary of Revenue is tasked with compiling an annual report on the child tax credit, detailing the number of recipients, adjusted income thresholds, aggregate credit amounts, and an analysis of the credit's effectiveness. The provisions of this section are supplemental to the existing Kansas income tax act.
